So let's say we implemented this and the government suddenly receives billions of credits from wealthy individuals. Would anything actually change? Is this what's holding us back from repairing all the roads to a fine standard? From implementing universal basic income?

It seems to me that if one tried to actually spend those credits we'd simply get inflation. Prices for roads, food etc. would just go up.

We definitely want to work on inequality, but I think numbers above 1B net worth are just weird quirks of the system. Musk is powerful because he's powerful, the number is just a reflection of that. Keeping his number below some arbitrary threshold isn't going to combat his power.

We need to tackle the problem head on: we need to stop individuals from amassing so much power. We get lost in this stupid abstraction called money. It's not what matters.
